BALlNG-PRESS.

v SPECIFICATION forming part of Letters Patent No. 410,473, dated September 3, 1889.

Application filed February 5, 1889- Serial No. 298,758. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY L. WHITMAN, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement. inBaling-Presses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which-- Figure I is a horizontal section of the power end of the baling-press, showing the traverseroperating mechanism Fig. II is a similar view with the parts in a different position. Fig. III represent-s a device in elevation for lifting the front end of the press. Fig. IV is a top View of the same. Fig. V is an elevation of the power mechanism. Fig. V1 is a vertical section illustrating the operation of the trip device, and Fig. VII is a similar view showing the parts in a different position to that shown in Fig. VI.

My invention relates to certain improvements in presses for baling hay, straw, cotton, excelsior, 850.; and myinvention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, 1 represents the baling-chamber; 2, the traverser, and 3 the pitman.

The outer end of the pitman is provided with a rack 4, engaged by an oscillating racksegment 5, mounted loosely on a power-shaft 6. The shaft 6 is revolved continuously in one direction by a sweep 40, or other suitable mechanism or means for rotating the shaft; but the rack-segment 5 is automatically connected with and disconnected from the shaft, so as not to revolve continuously with the shaft, but when released to return and to always remain in contact with the rack on the pitman.

The traverser is shown in its receded position in Fig. I, and in pressing the material it moves from the position shown in this figure to that shown in Fig. II, and the rack-segment and pitman also move from the position shown in Fig. I to that shown in Fig. II.

On the heel of the rack-segment 5 is a projection, consisting, preferably, of a frictionroller '7, mounted in suitable ears or projections 8, secured to or formed upon the racksegment.

it. The lever has a downturned end 12, that,

when the lever is in normal position, engages the projection on the rack-segment 5. The lever has an upward projection 13.

A duplicate of the lever 9 may be located on the other end of the cross-piece at the opposite side of the shaft, as shown in Figs. I, II, and V.

Depending from the top 14 of the press is a projection, consisting, preferably, of a friction-roller 15, journaled in ears or lugs 16, formed upon or secured to the top 14.

The operation is as follows: The parts being in the position shown in Fig. I, power is applied to the shaft 6, and the traverser is forced forward by its connection with the lever on the cross-piece of the shaft, consisting of the pitman having the rack and the racksegment having the projection. The rack-segment is caused to turn with the shaft by means of the downturned end 12 of lever 9 engaging the projection on the rack-segment, as shown in Fig. VI. Just as the traverser reaches the limit of its forward movement and the end of the pitman 3 is almost or quite on a line drawn through the center of the traverser and shaft 6, the lever 9 is tripped by its upper end coming into engagement with the press projection, which moves it from the position shown in Fig. VI to the position shown in Fig. VII, and as soon as the lever is" thus disconnected from the rack-segment projection the traverser will rebound and force the pitman and rack-segment back to the position shown in Fig. I from that shown in Fig. II Without turning the shaft back, because the rack-segment is loose on the latter when released from the lever. As soon as the end of the lever passes the press projection, its lower end will drop, so that when it reaches the segment projection again it will be ready to act. The levers engage the segment projection alternately.

In this manner I constructavery cheap and effectual power for presses.

To keep the rack of the pitman in engagement with the rack-segment, I employ a suit able forward track or guard rail 17, secured to a lug 23 on the frame of the press at one end and to an arm 18 at the other end. The pitman is provided with a friction-roller 19, bearing against the track or rail. While this rail prevents the disengagement of the parts, it does not interfere with the operation of the press.

In case the parts should move so far that the point of bearin g between the rack-segment and pitman will be exactly or a little past the line drawn through the center of the traverser and the shaft 6, then the traverser would not rebound. To avoid this danger of the parts failing to operate in this respect, I secure a pin or rod 20, against which the pitman impinges just as the traverser has finished its movement. I locate a spring 21 between the head 22 of the pin and a lug 23, through which the pin passes. This spring is compressed by the pitman each time the traverser reaches the limit of its movement, as shown in Fig. II, and as soon as the triplevers are disengaged from the segment projection, as stated, the action of this spring would be to repel the pitman andthrow it off the center in such cases as those mentioned.

It will be understood that at the time a lever is tripped there will be very little or no pressure between it and the segment projection, for the reason that at this time the back-pressure of the traverser is on the shaft 6 as the pitman is nearly or quite on a line drawn through the center of the shaft and traverser.

24 represents a roller journaled on the frame beneath the pitman 3, and which supports the pitman vertically.

My invention is designed for what is known as a full-circle press, though it could be used, of course, with a half-circle press.

In Figs. III and IV, I have illustrated a means for adjusting the forward end of the baling-chamber, as cases may require. 30 represents part of the front axle, 31 represents the front end of the baling-press, and 32 repceive the lower end of a screw-rod 34, which passes through the cross-piece 32 and is provided wlth a non-circular end 35 to receive a wrench or crank. 36 represents collars on the rod to prevent its vertical movement. The lower end of the block 33, rests on the axle 30.

It will be seen that by turning the rod 31 in the proper direction the body of the press can be raised or lowered with relation to the axle.

Having thus described my invention, the following is what I claim as'ncw therein and desire to secure by Letters Patent:

1. The combination of a traverser, a pitman provided with a rack, a power-shaft, an oscillating rack-segment loosely mounted on the shaft and meshing with the pitman-rack and having a projection, a pivoted lever engaging the segment projection at one end, and a press projection against which the other end of the lever impinges, substantially as described.

2. The combination of a traverser, a pitman provided with a rack, a power-shaft having a cross-piece rigidly secured thereto, provided with a pivoted lever, and an oscillating rack-segment loosely mounted on the shaft and meshing with the pitman-rack, having a projection with which thelever engages. substantially as described.

3. The combination of a traverser, a pitman provided with a rack, a power-shaft hav-' lower end 12 and upper end 13, an oscillating
